Hi again, I thought I could try and just live with the noise after 3 mechanics couldn't figure out what was causing the rattle. So this morning I decided to record the noise while I was on my way to work. Hopefully everyone can hear it but it happens after 10 seconds more or less. You will hear a metally banging noise. can anyone think of anything that his could be? Or has anyone ever had a similar noise? Desperate now.
